Tackle demanding fastening tasks with confidence using the Wera 855/4 imp DC Impaktor PZ3 bit in 50 mm length. Built with a standard 1/4" hexagon drive, this bit is engineered to withstand the extreme torque peaks generated by impact drivers. Its specialised torsion zone cushions heavy loads to prevent premature breakage, while the diamond particle coating bites securely into the screw recess to reduce cam-out and slipping. With the clear Take it easy colour coding system, you can spot the right PZ3 profile instantly in your tool collection. It provides the reach, grip, and durability needed to drive large timber and construction screws smoothly.
High quality bits for Pozidriv* screws. The Impaktor technology offers an above-average service life even under extreme circumstances. Enhanced friction resistance, thanks to the rough diamond-particle coating on the bit tip, prevents any slipping out of the screw head. Particularly suitable for use with customary impact drivers. 1/4" hexagon, suitable for holders as per DIN ISO 1173-F 6.3. * Pozidriv = registered trademark of European Industrial Service Ltd.
